Node.js 节点js请求代理

我通过代理发送请求，并且总是收到这样的响应

tunneling socket could not be established, cause=read ECONNRESET

或

我的代码

      let settings = {
    url: `url`,
    headers: {
      'Connection': 'keep-alive',
      'User-Agent': "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Safari/537.36"
    },
    method: 'POST',
    proxy: `http://${ip}:${port}`,
    strictSSL: false
  }
request.request(settings, (err, response, body) => {
 // err here
})

我做错了什么

现在出现以下错误：错误：隧道创建失败。套接字错误：错误：读取EconReset

我的代码：

  const request = require('request'),
  proxyingAgent = require('proxying-agent');

)

关于代码，问题可能在于

设置

对象。
您需要使用如下语法：

let settings = {
  url,
  headers: {
  'Connection': 'keep-alive',
  'User-Agent': "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Safari/537.36"
  },
  method: 'POST',
  proxy: `http://${ip}:${port}`,
  strictSSL: false
}

在这里，我们使用ES6来缩短对象。

但是，您也可以与npm包建立代理连接。
您的代码应该如下所示：

const proxyingAgent = require('proxying-agent');
const fetch = require('node-fetch');

const host = <your host>;
const port = <port>;

const creds = {
  login: 'username',
  password: 'pass'
};

const port = <proxy port>;

const buildProxy = (url) => {
  return {
      agent: proxyingAgent.create(`http://${creds.login}:${creds.password}@${host}:${port}`, url)
  };
};

//If you don't have credentials for proxy, you can rewrite function

const buildProxyWithoutCreds = (url) => {
  return {
      agent: proxyingAgent.create(`http://${host}:${port}`, url)
  };
};

@我想问题在于对代理的身份验证。EconReset错误表示连接错误。EconReset表示TCP会话的另一端突然关闭了其连接端。这很可能是由于一个或多个应用程序协议错误造成的。因此，我建议您检查是否需要用户名/密码等凭据来访问代理。

let settings = {
  url,
  headers: {
  'Connection': 'keep-alive',
  'User-Agent': "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Safari/537.36"
  },
  method: 'POST',
  proxy: `http://${ip}:${port}`,
  strictSSL: false
}

const proxyingAgent = require('proxying-agent');
const fetch = require('node-fetch');

const host = <your host>;
const port = <port>;

const creds = {
  login: 'username',
  password: 'pass'
};

const port = <proxy port>;

const buildProxy = (url) => {
  return {
      agent: proxyingAgent.create(`http://${creds.login}:${creds.password}@${host}:${port}`, url)
  };
};

//If you don't have credentials for proxy, you can rewrite function

const buildProxyWithoutCreds = (url) => {
  return {
      agent: proxyingAgent.create(`http://${host}:${port}`, url)
  };
};

const proxyGetData = async (url, type) => {
   try {
       const proxyData = buildProxyWithoutCreds(url);
       // Make request with proxy. Here we use promise based library node-fetch
       let req = await fetch(url, proxyData);

       if (req.status === 200) {
         return await req[type]();
       }
       return false;
    } catch (e) {
      throw new Error(`Error during request: ${e.message}`);
    }
  };
